"
Children of the Grave" is a song by
Black Sabbath from their 1971 album
Master of Reality. The song lyrically continues with the same anti-war themes brought on by "
War Pigs" and "Electric Funeral" from
Paranoid, adding in Geezer Butler's pacifist ideals of non-violent civil disobedience. Two previously unreleased versions of this song are released on the deluxe edition of
Master of Reality. The first is a version with alternate lyrics, the second an instrumental version.
